Faahfaahinta casharka

Natiijada casharka

Waxaan sharxi karaa sifooyinka kiimikada iyo jirka ee curiyeyaasha kala duwan.

Hordhac

Waxaan ku soo dhaweynayaa casharkayaga maanta oo ku saabsan sifooyinka curiyeyaasha (properties of elements). Waa qayb ka mid ah cutubka atamka, curiyeyaasha, iyo isku-dhisyada. Kahor intaadan daawashadan bilow, waa inaad hore u garanaysaa in curiyeyaashu yihiin walxo saafi ah oo aan si fudud loo kala jabin.

Muuji qoraalka
Elements are chemically pure, but can react together. Each element has a fixed melting point and boiling point. Each element has particular physical properties. Each element has particular chemical properties. The properties of elements are different from those of a single atom.

    • jajaban (brittle)
    • heer-kulka dhalaalidda sare (high melting point)

  1. 1. Maxay sababta u ah in curiyeyaasha (elements) ay leeyihiin heerkulka dhalaalida iyo karkarinta oo go'an?

    • Waxay beddelaan midabka heerkul gaar ah.
    • Jawaabta saxda ah:Waa walxo saafi ah (pure substances).
    • Waxay falgalaan kiimiko heerkulkan.
    • Waxay ku milmaan heerkulkan.

  2. 2. Waa kuwee kuwan soo socda ee ah sifooyin jireed (physical properties) ee curiye (element)?

    • adkaanta
    • dhalaalka
    • Jawaabta saxda ah:gubashada

  4. 4. Run ama been? Falcelinta kiimikada (chemical reactions), walxo cusub had iyo jeer waa la sameeyaa.

    • Jawaabta saxda ah:Run
    • Been
